  Oligothiophene compounds inhibit the membrane fusion between H5N1 avian influenza virus and the endosome of host cell

  摘要：

  Hemagglutinin (HA) which is essential for influenza viral infection and replication has become a target for the design of anti-influenza drugs. A novel series of oligothiophene compounds focused on the target were synthesized as specific inhibitors against the H5 subtype of influenza A viruses because oligothiophene has Pi-Pi stronger pep interactions with residues F110(2) and M24(1) of HA2 side chains. Oligothiophene compounds were designed and synthesized by a series of alkylation, azidation, amination and amidation reactions. The entry inhibitory activities of those compounds were tested at a cellular level against H5N1 influenza pseudovirus. Compound 3sf was revealed as the most active inhibitor in this series with an IC50 of 0.029 mM. The activity of 3sf is almost 1000 times that of the positive reference compound (CL-385319). A structure-activity analysis of these compounds demonstrated that the size of the oligothiophene compounds was very important for the inhibitory activity. Four compounds (3sk, 3sf, 3sc and 4sc) of strong inhibitiory activity against H5N1 influenza pseudovirus were assessed against H1N1 influenza virus MDCK. They also showed strong inhibitiory activity with IC50s of 3.292 mu M, 1.240 mu M, 1.119 mu M and 0.768 mu M, respectively. (C) 2017 Elsevier Masson SAS. All rights reserved.

  The chemoselectivity of halo(het)arene sulfonyl halide aminations is studied thoroughly under parallel synthesis conditions, and the scope and limitations of the method are established. It is shown that SNAr-reactive sulfonyl halides typically undergo sulfonamide synthesis during the first step; the second amination is also possible provided that the SNAr-active center is sufficiently reactive.

  在平行合成条件下深入研究了卤代（杂）芳烃磺酰卤胺化物的化学选择性，并确定了该方法的范围和局限性。结果表明， SN Ar反应性磺酰卤通常在第一步中进行磺酰胺合成；如果SN Ar活性中心具有足够的反应性，则第二次胺化也是可能的。相反，带有芳基化部分的磺酰氟在适当的控制下在后一个反应中心发生选择性转化。进一步的硫-氟化物交换（SuFEx）也是可能的，这对于某些磺酰卤类特别有价值。开发的两步并行双胺化方案提供了对 66.7 亿个化合物的合成可处理 REAL 型化学空间的访问（预期合成成功率 76%）。
